WILLIALVE R. BEATTY, OF HAMMOND, INDIANA.

LONG-STROKE VERTTCAL-TYPE PMlSS.

i Application led May 28,

Tonlfl -wwm t may concern Be it known that I, WILLIAM R. Bnn'rrr, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Long-Stroke Vertical-Type Presses, of which the following is a specification, reference being had therein t0 the accompanying drawings.

This invention relates to a long-stroke vertical-type press, and the object of the invention is the construction of a machine in the class of presser or bulldozers, which comprises a minimum of parts, and which is simple and eicient in operation, and

A in which press the power is exerted through a pulling instead of a compression motion.

lith this and other objects in view, my invention comprises certain novel combinations, constructions and arrangements of parts as will be hereinafter described, illustrated in the accompanying drawings, and more particularly pointed out-in the appended claims.

In the drawings:

Figure 1 is a view, in side elevation, partly in section, of a long-stroke verticaltypepress, constructed in accordance with the present invention, while Figure 2 is an end view of the press, showing the adjusting device partly in section.

Figure 3 is a view, taken on line 3 3, Fig, 1, and looking in the direction of the arrows, and showing some of the parts in section. n

Figure 4 is a bottom plan view of the mechanism with the clutch structure shown assembled with the main part of the press.

Figure 5 is a diagram of the press, showing the `lower position of the movable ram or die-holder, while Figure 6 is also a diagram, showing the ram or die-holder in its upper or highest position. y

Referring to the drawings by numerals, 1 Vdesignates the frame'of the press, including the horizontal table or stationary dieholder 2, the vertical guide housings 3, and the connecting top arch 4. f

A movable ram or die-holder 5 is slidably mounted, at its ends, in the vertical guide housings 3. A counterbalance cylinder 6 is mounted on the top arch 4, and connected to the piston rod 7 of cylinder 6, is a cross bar 8. A rod 9 is in the middle of the ram or die-holder 5, and links 10 are connected,

at their ends, to bar 8 and rod 9. A pipe 11 is' connected at one end to cylinder 6 and its other end is' connected to an air tank (not shown); when the die-holder 5 moves upwardly to its highest position (Fig. 6) upon the, frame, air from the tank will rush through pipe 1l into the tank under its piston, and if the air is under pressure, it will assist in raising the die-holder 5; when the die-holder 5 is lowered, as shown in Fig. 5, the air in cylinder 6 will be forced through pipe 11 to the tank (not shown), the air in cylinder 6 acting as a cushion, and the pressure in the tank can be maintained, by the operator, sufficient to counterbalance the movable ram or die-holder 5, so that the raising (Fig. 6) of said movable ram or dieholder will not necessarily require considerable power.

To operate the movable ram or die-holder, a primary shaft 12 is mounted upon the lower portion of frame l, and near each end is secured primary gears 13. An intermediate shaft 14 is journaled upon the frame, and a small cogor gear 15 is secured to the shaft and meshes with the primary gear 13 (Fig, 2). A driving gear 16, and a reverse gear 17 (Fig. 4) are mounted upon shaft 14. A motor drive shaft 18 is supported contiguous to intermediate shaft 14, and this shaft 18 is provided with gear 19 meshing with gear 16, and gear 2O meshes with an idler gear (not shown), which in turn meshes with gear 17. A forward clutch 21 and a reverse clutch 22 is slidably mounted upon drive shaft 18, and by swinging lever 23 in one direction, the forward clutch willA be operated to drive the machine in one direction, and upon swinging lever 23 in a reverse direction the reverse clutch 22 will be operated to cause the machine movement to be reversed. When power is imparted to the machine, the primary gears 13 will be rotated, thereby moving the connecting rods 24 in a vertical plane these rods are connected, at 25, to the primary gears 13, and their upper ends are pivotally connected, at 26, in bifurcated extensions 27 of the threaded bolts 28; said bolts 28 are mounted in the ends of the movable ram or die-holder, and on these bolts are mounted adjusting nuts or worm-sleeves 29; these nuts or sleeves 29 have worm-threads on their outer surface,

meshing with the horizontal worms 30,

which worms are fastened to the operating rod 31 that extends through the dle-holder 5, and upon the ends of which rod are handwheels 32. By rotating the rod 3l., at either end of the machine, the take-up o adjusting devices for the connecting rods, 2a, will be operated. By means of these two adj usting devices at the ends of the movable ram or die-holder, any unnecessary `slack between dies can be removed, or if the nature of the work requires, the available die space may be increased or decreased at will.

It is to be understood that on, or attached to, the stationary die-holder 2 and movable die-holder 5, are placed dies or devices to be used in the work.

llVhen the work is placed between the stationary die-holder 2 and the movable dieholder 5 and the machine started for bringing die-holder 5 downward, with a pulling action, will cause the downward movement of die-holder 5, which is a very eicient result, not heretofore obtained in the longstroke vertical-type press. Further, I have provided adjusting` means for connecting the connecting rods to the movable dieholder, whereby any slack can be taken up, or the distance of the movable die-holder with respect to the stationary die-holder, can be varied at the will of the operator, and I have also provided, in a vertical-type press of the kind described, a counterbalancing means, which counterbalancing means includes the cylinder 6 and its coordinate` arts.

p The function of parts 28, 29, 30 and 31 is to form a connection between ram 5 and connecting rods 24. They also serve to increase or decrease the die space between the ram 5 and table or die-holder 2. By rotating the shaft 3l, carrying` the worms 30, which in turn rotates adjusting nuts or sleeves 29, this will move the ram or dieholder 5, up or down as desired to suit various thicknesses of dies. The Vlower part of bolt 28 is supported by the walls of dieholder 5, as at Pg and the upper part as at CB-77 The function of the air cylinder 6 is to counterbalance the ram and attached parts, preventing them from descending of their own weight when the press is at rest.

'I believe that my machine is the only one in which power is applied to original high speed shafting and transmitted tothe movable ram or die-holder through a plurality of shafts and clutches through certain (le-- sign of gearing and from there through connecting rods.

Wfhile I have dcscribedthe preferred embodiment of my invention, and have illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same and I, therefore, reserve the right to make such alterations or changes as shall fairly fall within the scope of the appended claims.
